WHEEL AND TIRE THEREFOR.

Specification of Letters Patent.

Application filed November 15, 1907.

Patented June 21, 1910.

Serial No. 402,229.

To all whom it may concern:

Be it known that I, GEORGE D. Moons, a citizen of the United States,residing at lVorccster in the county of Worcester and State ofMassachusetts, have invented a new and useful lVheel and .Tire Therefor,of which the following is-a specification.

This invention relates to a tire or shoe for automobiles and similarvehicles and to a new and improved means for applying the same to awheel.

The principal objects of the invention are to provide a constructionwhich can be used with a form of tire of such a nature that no innertube will be required; to provide means whereby a new tire previouslyinflated can be carried on the machine and put in position in a veryconvenient manner when desired,

thus saving the time required in pumping up the tire after it is inplace; to provide for put-ting the tire in position in a rapid manner;to provide improved means for securing the tire whether of single ordouble tubctype to the wheel; and generally to improve the constructionand means for attachment of tires and shoes of the general characterreferred to.

Reference is to be had to the accompanying drawings which show preferredforms of the invention and in which,

Figure l is a seetionafl penspcctive view of a portion of a tire andfastening arrangement as applied to a wooden felly. Fig. 2 is a plan ofthe attaching devices with the tire removed. .Fig. is'a fragmentary sideelevation of the tire itself. Fig. 1 is a similar view showing amodification. Fig. 5 is a view similar to Fig. 1 showing certainmodifications and especially adapted for use on all-mctal wheels, andFig. 6 is a section of another modification.

Referring first to the first three figures, it will be seen that theinvention is shown as applied to a wheel having a wooden folly 10. Thisfolly is provided with a flange 11 at one side thereof which in thisinstance preferably is formed on a rim 12 surrounding the folly andsecured thereto by a series of bolts 13 or in any desired manner. Thisllangc' 11 is shown in Fig. l as extending outwardly from the surfaccvof the folly beyond the edge thereof. ()n the opposite side of the follya removable plate or ring 14 is secured by means of bolts 15 or thelike. The heads of the bolts all bear against 'this cause. either llatin the form shown in Fig. 2 or curved as m the form indicated at 220 ina plate or plates 16 on the other side of the felly this plate beingshown allin one piece so as to constitute a ring although it performsthe ollice of a plurality of washers. In order tokeep the plate inposition when the bolts are removed, it is held on the felly by means ofscrews 17 or the like.

The removable plate or ring ll is provided with a flange 20 similar tothe flange 11 and located "exactly opposite it. In the form shown inFig. 1, this flange is offset from the main portion of the plate 15 soas to provide a wide space between the flanges for the tire. Both ofthese flanges preferably are provided with outwardly flaring edges 21and with wide projections These projections extend from each flangetoward the other a considerable distance, preferably about onethird ofthe way across the space between the flanges. Preferably they arelocated alternately as indicated in Fig. land are of sullicient widthtin-d length so that they furnish wide surfaces for engagement with thetire to prevent the tire from being torn away from its support. Onaccount of the broad bearing surfaces of these projections or lugs,

the tire is securely held so as to prevent any creeping of the tirearound the rim and the lugs or projections are of-such strength as toavoid all danger of any breakage from The broad bearing surf-arcs areFig. 1, for example.

in the preferred form of the invention, the. tire 25 is provided with acorrespomlmg series of cavities or depressions 26 or 260 formed in theopposite sides of an inwardly projecting extension 27 which fits withinthe space between the llanges l1 and 20 both of which are shown offsetfrom the side of the felly. These depressions 26 or 2130 obviously arelocated alternately on the two sides of the flange when the projccti usor lugs 22 or 220 are alternate, and being permanently formed in thetire when the same is made,

the projections lit them when the tire is put in place in such a waythat creeping or any other disarrangement of the tire isolt'ectuallyprevented. This is considered as an important improvementover those construe tions in which sharp pointed pins are formed on thetire holding run to puncture the rubher and hold the tire. in thesecoustrluzlious the creeping of the tire is notcll'r-r-lually preventedas on account of their sharp points and edges the pins will cut therubber instead of preventing motion thereof. in the presentconstruct1on, the broad surfaces which are presented to resist motion ofthe tire in all directions relative to the rim, etl'ectually accomplishthe desired result. 1t is preferred also to line the depressions orcavities with sheet metal linings 28 or 280. These can be placed in thecavities before the final vulcanization and secured thereto during that'process or may be secured by .being flanged over in the ordinary way soas to be clenched into the rubber as indicated at 50 in Fig. {5. Theyafl'ord additional means for prevent'ihg any rupture of the tire at thispoint and hold the same in position. On account of the use of thesemetal linings, the number of lugs or depressions can be madecomparatively small although in Fig. 2, they are shmvn as about sixinches apart around the circumference of the wheel. The linings can beomitted however, or they can extend all the way through the extension 27as indicated in Fig. 6.

Although the tire can be made in the usual way as indicated in Fig. 5with the inner tube 29, the device can be constructed so that no innertube will be required. For this purpose the outer tube or shoe is firstmade in the usual Way with the depressions or cavities, and sheet metallinings if desired, and then it is put in the mold after the entirestructure is completed and the edges corresponding to the edges 30 shownin Fig. 5, placed in contact with each other, with a rubber cementbetween them if necessary, and sealed by vulcanization so that thestructure then constitutes a single tube tire which can be inflated inthe usual way through a valve 31.

The tire can be provided with any desired kind of armor or protectingdevices but these are not shown as they constitute no part of thepresent invention. By constructing a tire in this way, the expense forthe inner tubes is saved and there will be no necessity of watching theinner tube to see that it does not get pinched between the edges 30while pumping it up or attaching the bolts. Furthermore, the tire can becarried on the machine in an inflated condition and no pumping up, withthe corresponding waste of time, will be required when a new tire is puton.

' In attaching the inflated tube, the plate 14 is first removed, leavingthe plate 16 and bolts 15 in position, the old tire is then drawn oilsidewise and the new inflatedtire slipped on the rim 12 in properposition so that the projections 22 011 the flange 11 will enter thedepressions 26 on that side of the tire. The only other operationnecessary is to apply the plate or ring 14 and tightenup the nuts on thebolts 15. In this way the tire is effectually clenched between theflanges 11 and 20, which ,clenching act1on 1s assisted by the lugs,which hold the tire in position to prevent it from creeping or otherwiseworking loose.

It will, of course, be understood that this invention is capable ofbeing carried out in many ways other than that illustrated in Fig. 1.One of these other forms is indicated in Fig. 5 in which a wheel is reresented having a metallic felly 40 provided with an integral flange 41and a removable plate 42 on the other side having a flange 43 thereon,opposite the flange 41. The plate 42 is held in position by bolts 44 andthe flanges 41 and 43 are provided with projections or lugs 45 which canbe of the same shape and size as those shown in the other figures. Inthis case a double tube tire is shown having an inner tube 29 and theinwardly projecting extension of the shoe is provided with a sheet metalcasing 46 which is provided with off-sets which constitute linings 47fitting in the depressions in the tire. These modifications come withinthe scope of this invention.

I am aware that the invention can be carried out in many other formswithout departing from the scope thereof as expressed in the claims.Therefore, I do not wish to be limited to the particular constructionsshown, but

What I do claim is 1. The combination of a wheel, and a felly having aflange extending outwardly from one side of the telly parallel to theplane of the wheel, with a removable plate on the telly opposite saidflange said plate and flange having wide-faced projections on theirinner faces extending transverse to the plane of the wheel, and a tireprovided with an extension in the plane of the wheel having permanentmolded cavities or depressions'on opposite sides thereof for recelving"said projections.

2. In a tire holding device for a wheel, the combination of two clencherflanges each having wide-faced projections arranged on the inner facethereof and extending toward the other flange, a tire having an inwardlyprojecting extension fitting betw en said two flanges and provided withpermanent dGPT'GSSlODS or cavities registering with said pro ections.

3. The combination with a wheel having a felly, of a flange extendingoutwardly from the telly near one edge thereof and held rigidly thereon,a ring removabl secured to the opposite side of said felly independentlyof said flange and havin an offset flange opposite the first nameflange, wide-faced projections extending from the inner faces of saidflanges, means folly Opposite the removable flange for receiving theheads of bolts for securing the on the.

senses arranged on the inside surfaces thereof, a

tire clenched between said flanges and provided with alternatelyarranged depressions or cavities and registering with said projections,and sheet metal linings in said ;eavities.

,5. A tire having a circular extension projecting toward the axisthereof and prov ded on its opposite sides with permanent moldeddepressions or cavities having Wide faces,

therein. 7

A tire having an extension pro3ect1ng toward the axis thereof andprovlded on '1 provided with sheet. metal linings its opposite sideswith depressions or cavities having wide faces provided with sheet metallinings therein secured 1n the depressions or cavities by vulcanization.

7. A tire having a solid extension projecting toward the axis thereof,and having permanent depressions or cavities in its side surfaces.

8. A tire in the general form of an outer tube or shoe having twoopposite extensions secured together to form a seal, and-havingpermanent depressions or cavities in their opposite outer sides.

In testimony whereof I have hereunto set m v hand, in the presence oftwo subscribing witnesses.
